Abstract
Coordination information for controlling base-station-to-base-station interference is transmitted from one radio network node () (e.g., an LTE eNodeB) to another, using certain parts of the TDD subframe. One example method, as might be implemented in a radio network node () such as an LTE eNodeB, includes the generating () of a TDD coordination signal and the transmitting () of the TDD coordination signal to one or more other radio network nodes. In some embodiments, the coordination signal is transmitted in a guard period of a special subframe at the target node. In others, the coordination signal is transmitted in another interval during which the receiving node is not transmitting, such as in uplink subframe for the receiving node, an uplink portion of a special subframe at the receiving node, or in a downlink subframe or downlink portion of a special subframe during which the receiving node is not transmitting.
